Overview

Product Details

Demonstration circuit 1821B features the LTC3114-1, a wide operating range synchronous monolithic buck-boost converter with programmable average output current. DC1821B operates with a 2.7V to 40V input voltage range. The demo board has been designed with the output voltage set to 5V and can provide up to 1A output with VIN > 6V. It features two user selectable operating modes: Burst Mode® operation and Fixed Frequency PWM (JP2). There is also an accurate programmable RUN pin which is used to ENABLE the converter (JP1).


The LTC3114-1 uses average current mode control to simplify voltage loop compensation and provide good line and load transient response. It incorporates a proprietary low noise switching algorithm which optimizes efficiency with input voltages above, below or equal to the output voltage and ensures seamless transitions between operating modes.
